A polymer is provided according to structure (I) wherein Y is a thiol-reactive group selected from one or more of the following moieties and Z is an ionogenic group selected from one or more of the following moieties. The surface of a polymeric substrate is modified by contacting the surface with a polymer according to structure II or structure III and exposing the surface to ultraviolet light.

A mass spectrometric approach for rapid and simultaneous detection of several single nucleotide polymorphisms (SNPs) is reported. Oligonucleotide single base extension (SBE) primers, labelled at the 5′-end with photocleavable, quaternised and brominated peptidic mass tags, are extended by a mixture of the four dideoxynucleotides of which one is biotinylated. The 3′-biotinylated extension products are captured by streptavidin-coated solid phase magnetic beads, whilst non-biotinylated extension products and unreacted primers are washed away. Quaternised and brominated mass tags, cleaved from captured extension products during analysis by matrix-assisted laser desorption/ionisation-time-of-flight (MALDI-TOF) MS, are detected at pmol levels. This method is applied to the analysis of mitochondrial DNA polymorphisms for the purpose of human identification.
报告采用一种质谱方法,可同时快速检测多个单核苷酸多态性(SNPs)。寡核苷酸单碱基延伸(SBE)引物的 5′端标记有可光裂解、季铵化和溴化的肽质量标签,由四种双脱氧核苷酸的混合物延伸,其中一种是生物素化的。链霉亲和素涂层固相磁珠可捕获 3′-生物素化的延伸产物,而非生物素化的延伸产物和未反应的引物则会被洗去。在基质辅助激光解吸/电离飞行时间质谱(MALDI-TOF)分析过程中,从捕获的延伸产物中裂解出的季铵化和溴化质量标签可在 pmol 水平上进行检测。该方法被应用于线粒体 DNA 多态性分析,以实现人类身份识别的目的。
